The invention "a capture device for hydraulic transmitted wetland plant seeds and method thereof' belongs to the ecological engineering field. The capture device is characterized by comprising a buoyant base and at least 1 tapered mesh enclosure; the tapered mesh enclosure is a tapered structure with bottom surface open, and its tapered surface is provided with a plurality of meshes; a structure allowing water and plant seeds to penetrate in but preventing the plant seeds from penetrating out is set on the mesh; the bottom surface of the tapered mesh cover is connected to the top surface of the buoyant base; the capture device can be fixed at a certain position in water through a fixed part; the buoyancy F provided by the buoyant base satisfies the following condition: Gd -0.8 × .rho.w gVd<=Ff <=Gd - 0.4 × .rho.w gVd; The Gd refers to the weight of the capture device, the .rho.w refers to the water density, the g is the gravity coefficient, and the Vd refers to the capture device volume. The number of seeds captured by the device and method of this invention is several times more than the prior method.
